Did you disconnect the battery to reset the code? Now if you did. Mr. Robinson has a series of tests on his site you can follow. http://www.robisonservice.com/servicedep/rover_trouble.asp   Aaron Richardet (Draaronr) Senior Member Username: Draaronr Post Number: 481 Registered: 09-2002 Posted on Sunday, February 29, 2004 - 07:57 pm:    Check your TPS. if it is high mileage there is a good chance that it is going bad.   Wes (Wes) Member Username: Wes Post Number: 239 Registered: 02-2002 Posted on Sunday, February 29, 2004 - 10:49 pm:    Disconnecting the battery is not the proper way of reseting the codes. To reset codes... Clearing the display 1. Switch ignition on. 2. Disconnect serial link mating plug, wait 5 seconds, then reconnect. 3. Switch ignition off, wait for main relay to drop out. 4. Switch ignition on. The display should now be reset. If there are other faults, the next one will be displayed. Otherwise the display will be black 5. If there is more than one fault repeat steps 1 to 4, to clear each fault until the display is blank. The serial plug should be under the glove box(?) Can anyone confirm that? It's been awhile since I've done a reset.
